Mattk 0 Report post Posted May 4, 2018 Please help. I have a 1986 318i (E30) that is extremely heavy on fuel. Dont even get 250km on a tank. Cheers Quote Share this post Link to post Share on other sites
gjm 3258 Report post Posted May 4, 2018 Obviously should be better than that, regardless of gearbox. I'm assuming you have the 1.8 M10 engine? What gearbox do you have? How well-serviced has it been? First thing to check on a M10 with poor economy is for vacuum leaks. Without vacuum, the K-Jet will keep throwing fuel through as it thinks it is needed.
